Yintoni itekhnoloji ye-ADSL kwaye isebenza njani?
I-ADSL sisifinyezo somgca wokubhaliswa kwedijithali ye-Asymmetric
(Umgca wobhaliso we-Asymmetric Digital)
Yinkonzo ebonelela ngonxibelelwano olubanzi lwe-Intanethi.
Olu lolona hlobo luxhaphakileyo kunxibelelwano lweDSL olusebenzisa iingcingo esele zibekelwe inkonzo yefowuni kwaye oku kuyenza ukuba ibe lukhetho oluncinci nolusebenzayo lokuhambisa unxibelelwano lwe-Intanethi emakhayeni, ngakumbi njengoko ibonelela ngesantya esiphezulu malunga namaxesha angama-30-40 ngokukhawuleza kunesiko ukucofa imodem uqhagamshelo, kwaye usebenzisa uluhlu olubanzi lokuhamba.
Kwitekhnoloji ye-ADSL akukho ntlawulo ngokwexesha okanye nayiphi na intlawulo yoqhagamshelo ukuze ibizwe njengesiqhelo-kwitekhnoloji, apho ikhompyuter inokudityaniswa khona ngokusisigxina kwi-Intanethi ngesixhobo se-ADSL okanye kwimodem ebanzi.
Umgaqo osebenzayo we-ADSL
Umgaqo wetekhnoloji ye-ADSL ilula kakhulu kwaye ibandakanya ukuhambisa idatha ngenxalenye yeengcingo zobhedu zomgca othile womhlaba;
Oko kukuthi, ucingo lobhedu lunomthamo omkhulu kunokuba lusetyenziselwe ukufowuna nje, ngoko ke i-ADSL isebenzisa esi sithuba songezelelweyo kwaye yahlulahlula-hlula imvamisa ngaphakathi kocingo lobhedu lube ziinxalenye ezintathu.
Ngokubhekisele kwinxalenye yokuqala yocingo lobhedu yeyamaxesha asetyenziswa kwiifowuni ezisusela kwi-300 ukuya kwi-3400 Hz, ebizwa ngokuba yi-POT (Plain Old Telephone) kwaye yahlulwe ngokupheleleyo kwamanye amacandelo amabini ocingo lobhedu kusetyenziswa okhethekileyo ukukhupha isixhobo esiqinisekisa ukusebenza kakuhle kweencoko zomnxeba ukuba uqhagamshelo lwe-ADSL lume nangasiphi na isizathu.
Ngelixa inxenye yesibini yocingo lobhedu luluhlu lokuhambisa idatha, olunikezelwe ekuthumeleni idatha ukusuka kwicala lomsebenzisi kwinethiwekhi, okanye oko kubizwa ngokuba kukhuphelo.
Inxalenye yesithathu yocingo lobhedu kukhuphelo, okt ukusuka kwinethiwekhi ukuya kumsebenzisi, kwaye kufanele kuqatshelwe apha ukuba isantya sokukhuphela kwinethiwekhi kwimigca ye-ASDL siphezulu kakhulu kunesantya sokulayisha kwinethiwekhi kwaye nantsi into igama elithi asymmetric lithetha.
Zithini iimpawu ze-ADSL
● Itekhnoloji yokuqhekeka kwe-ADSL iluncedo kakhulu kwaye iluncedo, ungatsiba i-Intanethi ngelixa ufowuna ngaphandle kokulalana kwezi nkqubo zimbini.
● Itekhnoloji yoqhagamshelo lwenqaku, ukuya kwinqanaba, oko kuthetha ukuba uqhagamshelo lwakho luhlala luzinzile kwaye aluchaphazeleki yiyo nantoni na ukuba umboneleli we-Intanethi akayeki ukusebenza.
● I-ADSL ikunika intsebenzo engcono ye-intanethi xa kuthelekiswa ne-ISDN okanye uqhagamshelo lweemodem. Nge-ADSL, unokukhuphela amaxwebhu kunye namaphepha ewebhu kwaye uthumele i-imeyile ngokukhawuleza. I-ADSL iluncedo kakhulu kwiinkampani ukunciphisa iindleko zeminxeba yamanye amazwe.
● Ngokusebenzisa le nkonzo, awuyi kuzikhathaza malunga nemirhumo eyongezelelweyo okanye nayiphi na imali eyongezelelweyo onokuyifumana, kukho umrhumo wenyanga wobhaliso osisigxina ekufuneka uhlawule kwaye kuko konke oko, ngaphandle kwesixa sokusebenzisa kwakho i-Intanethi kuphazamisana nemali ekufuneka uyihlawule.
Zeziphi izinto ezingalunganga nge-ADSL
Ngaphandle kwezibonelelo zale nkonzo intle, ayisiyongxaki, esiya kuthi sizikhankanye, zezi:
● Isantya sonxibelelwano lwakho lwe-ADSL sichaphazeleka ngumgama osuka kwiziko lomnxeba, kokukhona umgama uphezulu, kokukhona ubuthathaka. Oku kwenza ukuba i-ADSL ingakulungeli ukusetyenziswa emaphandleni, apho ingafumaneki rhoqo, kwaye ukuba iyafumaneka ihlala ihlupheka.
● Itekhnoloji ye-ADSL ikwachaphazeleka linani labantu abasebenzisa umgca wakho, kwaye ukuba kukho inani elikhulu kunokubakho ukwehla okubonakalayo, ngakumbi ukuba abamelwane bakho banayo i-ADSL kwaye banemirhumo ngesantya esiphezulu.
● Isantya sokukhuphela kwinethiwekhi sikhulu kakhulu kunesantya sokufaka kwinethiwekhi, enyanisweni oku kungathathwa njengokubi kakhulu kubantu abahlala bethumela iifayile kwinethiwekhi, kunye nabantu abaneewebhusayithi ezibapapasha rhoqo.
● Iindleko ze-adsl zixhomekeke ekutshintsheni kakhulu kuba ababoneleli nge-intanethi baneenkonzo ezoneleyo kwinani elithile, kodwa ukwanda kwebango kuyabanyanzela ukuba bandise iinkonzo zabo kwaye oku kuya kubabiza kakhulu, ke iindleko ziya kutshintshwa kwaye le yinto into engacaciswa ngabanikezeli beenkonzo kubathengi
Kwaye usempilweni kwaye ukhuselekile kubalandeli bethu abathandekayo
